Simultaneous Ocean Acidification and Warming (Effects on Marine Animals: Miscellaneous) -- Summary (25 November 2014)
Most of the ocean acidification research conducted to date has focused solely on the biological impacts of declining seawater pH. Few studies have investigated the interactive effects of ocean acidification and temperature. This summary examines what has been learned in several such studies of various marine organisms that challenge the alarming and negative projections of the IPCC on the matter...

Global Warming Not Influencing Annual Streamflow Trends in the Southeast and Mid-Atlantic United States (21 November 2014)
Climate model simulations generally predict a future with more frequent and more severe floods in response to CO2-induced global warming. Confirming such predictions with real world observations, however, has remained an elusive task. The latest study to illustrate this point comes from the four-member research team of Barros et al. (2014), who writing in the Journal of Hydrologic Engineering analyzed streamflow records at various locations throughout the southeast and mid-Atlantic United States over the past century...

FACE Experiments (Grassland Species) -- Summary (20 November 2014)
The Free-Air CO2 Enrichment technique of studying the biological consequences of the ongoing rise in the air's CO2 concentration on different types of grasslands growing out-of-doors under close-to-natural environmental conditions reveals the several positive impacts of the anthropogenic-produced phenomenon...

Forest Topsoil Carbon Content: The Outlook for China and Beyond (17 November 2014)
The combination of (1) soil carbon accumulation and (2) vegetation carbon sequestration observed in various locations across the globe is triggering "a negative feedback to climate warming, rather than the positive feedback predicted by coupled carbon-climate models"...

Ocean Acidification (Effects on Marine Animals: Fish) -- Summary (14 November 2014)
As the air's CO2 content rises in response to ever-increasing anthropogenic CO2 emissions, and as more and more carbon dioxide therefore dissolves in the surface waters of the world's oceans, theoretical reasoning suggests the pH values of the planet's oceanic waters should be gradually dropping. The IPCC and others postulate that this chain of events, commonly referred to as ocean acidification, will cause great harm -- and possibly death -- to marine life in the decades and centuries to come. However, as ever more pertinent evidence accumulates, a much more optimistic viewpoint is emerging. This summary examines the topic of the potential impacts of ocean acidification on fish...

Plant Growth Database (14 November 2014)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Rye (Dahal et al., 2014)...

Temperature-Related Deaths in a Warming World (13 November 2014)
Over the course of 20th-century global warming, daily minimum temperatures typically rose at a rate that was fully three times greater than the rate of daily maximum temperature rise over most of the world, which resulted in a significant reduction in diurnal temperature range throughout the better part of the inhabited portions of the planet over that time period, which reduction likely significantly reduced the percentage of the human population dying each year from the various health challenges listed in this study...

Individual and Combined Effects of Warming and Ocean Acidification on Young Corals (12 November 2014)
The consequences of the "double whammy" are not what you might think they would be, as the authors of this study reveal there was "no consistent effect of elevated pCO2 on fertilization, development, survivorship or metamorphosis, neither alone nor in combination with temperature" of two important Great Barrier Reef corals...

Plants Climbing Mountains in Warming and CO2-Accreting Air (12 November 2014)
Former NASA scientist James Hansen has claimed in the past - in testimony before a committee of the U.S. House of Representatives, no less - that in response to CO2-induced global warming, plant life in alpine regions is "in danger of being pushed off the planet," as it gradually migrates upward in elevation in response to increasing temperatures. At first glance, this contention does not seem all that unreasonable. In fact, it actually sounds logical. But when assessed in "real time" in the real world, it is found to be something quite different...

A New Temperature History (AD 674-2010) of Southeast Finland (5 November 2014)
Taken in their entirety, the several observations presented in this study reveal the natural, and possibly solar-induced, warming and cooling and warming again that produced Earth's Medieval Warm Period, Little Ice Age and Current Warm Period, which phenomenon demonstrates that there is nothing unusual, unnatural or unprecedented about the Earth's current level of flat-lining warmth...

The Terrestrial Carbon Cycle in Eight CMIP5 Earth System Models (5 November 2014)
The eight most up-to-date ESMs are not up to the task of adequately representing the many biological and climatological phenomena that are required to correctly assess the current status of Earth's terrestrial carbon cycle or, much less, its future trajectory, as the atmosphere's CO2 concentration continues to rise...

Plant Root Growth Enhanced in a CO2-Enriched World of the Future (4 November 2014)
When it comess to plant roots, there is much more of good produced by atmospheric CO2 enrichment than what meets the eye; and it's down there, just beneath our feet, providing a firm foundation for significantly enhanced food production in the years and decades to come...

Cool Season Anomalous Temperature Regimes in CMIP5 Models (3 November 2014)
Once again have a situation where the very best of the world's climate models cannot predict, or even replicate, another pair of recurring temperature perturbations (CAOs and WWs), which in this case are unique to the United States...
